This is pretty simple:
I started with bone-in chicken thighs. Washed, dried, seasoned with a bit of salt and pepper. Placed in a baking dish, skin-side up, covered with foil and bake at 375 degrees for 20 minutes. Removed the foil and baked for an additional 15 minutes, brushed with favorite barbecue sauce every five minutes. Then baked for an additional 5 minutes. This allows the chicken to cook without burning the barbecue sauce and the additional 5 minutes let it get a nice coating.
If you’re grilling, grill for 20 minutes, turning the chicken several times before adding the barbecue sauce, allowing it to grill evenly. Turn skin-side up and add barbecue sauce. After you start brushing on the barbecue sauce you probably won’t want to turn it, keeps it from being too messy.
